摘要： Described are techniques for processing a request from a client. Validation processing is performed to determine whether any restrictions are violated. With respect to two associated objects for a logical device and its snapshot, a business logical provider may perform runtime checks regarding the two associated objects of the same or different frameworks to ensure a valid state exists with respect to the requested operation on the two associated objects. For example, the request may be to restore a logical device to its previous snapshot and the restrictions may indicate to not perform the restore if the logical device is in an active mirroring relationship, a source of an active migration, or if the snapshot has expired. The request may be to destroy the logical device which is included in a consistency group and a restriction indicates that a logical device included in a consistency group may not be destroyed.

摘要： Described are techniques for processing a request received at a business logic provider from a client. The request includes a snapshot identifier uniquely identifying a snapshot having a snapshot object in a first data model and requests properties of a storage device providing a data source for the snapshot identified by the snapshot identifier. The snapshot object is requested from, and returned by, a snapshot provider. The business logic provider requests, from a storage device provider using a first property of the snapshot object, a storage device object corresponding to the storage device identified by the first property. The storage device provider returns the storage device object to the business logic provider. The storage device object is then returned to the client.

摘要： A method is used in managing command line interface commands. Legacy CLI command information is received at a command line interface (CLI) provider. At the CLI provider, it is determined to convert the legacy CLI command information. The CLI provider has an adapter for performing the conversion. Updated CLI command information is derived by the adapter from the legacy CLI command information. The updated CLI command information is submitted to a plugin for processing.
